In a method for reminding using an electronic device, the method includes controlling a front camera of the electronic device to capture a facial image, determining whether a user needs to shave according to the characteristic information of a beard region of the facial image, and controlling a reminding device to remind the user to shave.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. An electronic device comprising: a front camera and a reminding device; at least one processor; and a storage device storing one or more programs, which when executed by the at least one processor, cause the at least one processor to: control the front camera to capture a facial image; determine a cheek region and a beard region from the facial image; extract characteristic information of the cheek region and the beard region from the facial image; compare the characteristic information of the cheek region and the beard region, and determine a difference value between the two regions; and upon determining that the difference value exceeds a predetermined threshold, control the reminding device to emit and alert to remind the user to shave, wherein the predetermined threshold comprises a first threshold which corresponds to a collection of relatively small differences, a second threshold which corresponds to a collection of relatively big differences, and a third threshold which corresponds to a collection of relatively significant differences.
An electronic device alerts a user to shave by using its front camera to capture a facial image. The device analyzes the image to identify cheek and beard regions, extracts characteristic information from both regions, and calculates a difference value between them. If this difference exceeds a predefined threshold (small, big, or significant), the device activates a reminder (like a sound or vibration) to prompt the user to shave. The device includes a processor, a front camera, a reminder device, and memory storing the analysis and reminder programs.
2. The electronic device as described in claim 1 , wherein the storage device further stores a relation list which defines multiple reminders corresponding to different difference values; wherein the at least one processor further acquires from the relation list a reminder corresponding to a relationship between the determined difference value and the multiple thresholds, and controls the reminding device to remind the user to shave using the acquired reminder.
The electronic shaving reminder device described previously also uses a stored relation list. This list links different calculated "beard versus cheek" difference values to specific reminders. Based on where the calculated difference falls relative to multiple thresholds in the relation list, the device picks a corresponding reminder and alerts the user to shave using that specific reminder. For example, a small difference might trigger a subtle reminder, while a large difference triggers a more obvious one.
3. The electronic device as described in claim 2 , wherein the reminder corresponding to the difference value which exceeds the first threshold is no action; the reminder corresponding to the difference value which exceeds the second threshold is selected from a group consisting of a first predetermined message displayed on a display screen, vibrating the electronic device in a first predetermined frequency, a first predetermined voice message read by a loudspeaker, and any combination thereof and the reminder corresponding to the difference value which exceeds the third threshold is selected from a group consisting of a second predetermined message displayed on a display screen, vibrating the electronic device in a second predetermined frequency, a second predetermined voice message read by a loudspeaker, and any combination thereof.
In the shaving reminder device using a relation list and multiple thresholds, the reminder system works as follows: No action is taken if the "beard versus cheek" difference only exceeds the first (smallest difference) threshold. If the difference exceeds the second threshold, the reminder is a message on the screen, a vibration, a voice message, or any combination. If the difference exceeds the third (largest difference) threshold, the reminder is a different message on the screen, a different vibration frequency, a different voice message, or any combination.
4. The electronic device as described in claim 2 , wherein the reminding device is selected from a group consisting of a display screen, a vibrator, a loud speaker, and any combination thereof, wherein the display screen is configured to display a predetermined message, the vibrator is configured to vibrate the electronic device, and the loudspeaker is configured to read a predetermined voice message.
In the electronic shaving reminder device, the reminder itself is a display screen that shows a message, a vibrator to vibrate the device, a loudspeaker to play a voice message, or any combination of these. The display screen shows a predefined message, the vibrator vibrates the device, and the loudspeaker plays a predetermined voice message to remind the user to shave.
5. The electronic device as described in claim 1 , further comprising: a housing; a razor head mounted on the housing; and a driving device positioned in the housing, the driving device configured to drive the razor head for shaving.
This electronic device not only reminds you to shave, but includes the hardware to do so. It contains a housing, a razor head mounted on the housing, and a motor (driving device) inside the housing that drives the razor head for shaving. It still includes the front camera and facial analysis of the previous claims for prompting shaving reminders.
6. The electronic device as described in claim 5 , wherein the at least one processor further controls the driving device to work, in order to drive the razor head for shaving.
This shaving device (with razor head and motor) can automatically start shaving. The processor, in addition to the facial analysis and reminder functions, also controls the motor to drive the razor head for shaving, presumably after determining the user needs to shave based on the image analysis.
7. The electronic device as described in claim 5 , further comprising a switch mounted on the housing, the switch configured to control the driving device to work in response to user's operation, in order to drive the razor head for shaving.
This shaving device (with razor head and motor) also includes a manual switch on the housing. This switch allows the user to manually control the motor, driving the razor head for shaving, regardless of what the facial image analysis shows. The switch overrides or supplements the automatic shaving reminder functionality.
8. A computer-based method for reminding using an electronic device, the method comprising: controlling a front camera of the electronic device to capture a facial image; determining a cheek region and a beard region from the facial image; extracting characteristic information of the cheek region and the beard region from the facial image; comparing the characteristic information of the cheek region and the beard region, and determine a difference value between the two regions; and upon determining that the determined difference value exceeds a predetermined threshold, controlling a reminding device to emit and alert to remind the user to shave, wherein the predetermined threshold comprises a first threshold which corresponds to a collection of relatively small differences, a second threshold which corresponds to a collection of relatively big differences, and a third threshold which corresponds to a collection of relatively significant differences.
A computer-based method for reminding a user to shave using an electronic device involves: Capturing a facial image with the front camera; Identifying cheek and beard regions in the image; Extracting characteristics from each region; Comparing the cheek and beard region characteristics to calculate a difference value; and if the difference exceeds a threshold (small, big, or significant), activating a reminder alert to prompt the user to shave.
9. The method as described in claim 8 , further comprising: acquiring from a relation list a reminder corresponding to a relationship between the determined difference value and the multiple thresholds, wherein the relation list is stored in the electronic device and defines multiple reminders corresponding to different difference values; and controlling the reminding device to remind the user to shave using the acquired reminder.
This shaving reminder method also uses a relation list stored on the device. This list associates different calculated "beard versus cheek" difference values with specific reminders. The method acquires a reminder from this list based on the calculated difference's relationship to the thresholds, and then uses the chosen reminder to alert the user to shave.
10. The method as described in claim 9 , wherein the reminder corresponding to the difference value which exceeds the first threshold is no action; the reminder corresponding to the difference value which exceeds the second threshold is selected from a group consisting of a first predetermined message displayed on a display screen, vibrating the electronic device in a first predetermined frequency, a first predetermined voice message read by a loudspeaker, and any combination thereof; and the reminder corresponding to the difference value which exceeds the third threshold is selected from a group consisting of a second predetermined message displayed on a display screen, vibrating the electronic device in a second predetermined frequency, a second predetermined voice message read by a loudspeaker, and any combination thereof.
In this shaving reminder method utilizing a relation list and thresholds, the reminder is determined as follows: No action if the "beard versus cheek" difference exceeds only the first threshold. A message, vibration, voice message, or combination if the difference exceeds the second threshold. A different message, vibration, voice message, or combination if the difference exceeds the third threshold.
11. A non-transitory computer-readable medium having stored thereon instructions that, when executed by at least one processor of an electronic device, causing the electronic device to perform a method for reminding, the method comprising: controlling a front camera of the electronic device to capture a facial image; determining a cheek region and a beard region from the facial image; extracting characteristic information of the cheek region and the beard region from the facial image; comparing the characteristic information of the cheek region and the beard region, and determine a difference value between the two regions; and upon determining that the determined difference value exceeds a predetermined threshold, controlling a reminding device to emit and alert to remind the user to shave, wherein the predetermined threshold comprises a first threshold having small difference, a second threshold having big difference, and a third threshold having significant difference.
A non-transitory computer-readable medium (like flash memory) stores instructions. When executed by a processor in an electronic device, these instructions cause the device to remind a user to shave. The method involves: Capturing a facial image using the front camera; determining cheek and beard regions; extracting characteristic information; comparing the regions to get a difference value; and alerting the user to shave if the difference exceeds a threshold (small, big, significant).
12. The non-transitory computer-readable medium as described in claim 11 , further comprising: acquiring from a relation list a reminder corresponding to a relationship between the determined difference value and the multiple thresholds, wherein the relation list is stored in the electronic device and defines multiple reminders corresponding to different difference values; and controlling the reminding device to remind the user to shave using the acquired reminder.
The computer-readable medium for the shaving reminder additionally includes instructions for using a relation list. This list, also stored on the device, associates different "beard versus cheek" difference values with specific reminders. The instructions acquire a reminder from this list based on the calculated difference and the thresholds, and then control the reminding device to prompt the user to shave using the selected reminder.
